Israel’s domestic security service says it has arrested a Belgian citizen of Iranian origin who it claims has admitted he was sent to Israel to spy for Iran.

A statement by the Shin Bet — the Israeli equivalent of the FBI — says Ali Mansouri, who entered Israel under the name Alex Mans, was sent by the Iranian Revolutionary Guard’s elite Quds Force to set up business ties in Israel as a front for spying.

The Shin Bet said Mansouri made three visits to Israel since 2012 in the guise of a windows and roofing salesman. The Shin Bet said Mansouri was caught with photographs he took of the U.S. Embassy in Tel Aviv.
